On a calamitous day for track and field, international sport and the idea of elite human endeavour generally, Tyson Gay, the fastest man in the world this year, and Asafa Powell, the second fastest, tested positive for banned substances. Both have denied cheating, not that this is any defence against a ban, and both are out of the world championships in Moscow. Powell joins four other Jamaicans to have tested positive at the national championships, while Gay has already blamed – of all things – somebody else. "Sometimes a human being naturally, generally trusts somebody," he said. Indeed they do, Tyson, indeed they do.

England women emulate men

England's women's team struck a blow for footballing parity by making a calamitous start to Women's Euro 2013 in Linköping, Sweden, losing 3-2 to Spain thanks to a 94th-minute own goal before rescuing a 1-1 draw with Russia with a last-gasp goal of their own. Hope Powell's team were unbeaten in the 16 months leading up to the competition but now risk perfecting the English tournament art of troughing at the right moment. Meanwhile Mohamed Al-Fayed has sold Fulham to US billionaire Shahid Khan for $300m. Good news for Fulham fans though: Fayed has stipulated the club's statue of Michael Jackson must remain untouched. "I wouldn't pass this club to any junkie," Fayed added, clearing that one up.

Not so mellow yellow at Tour

The Tour de France continues to enthral and appal: Mark Cavendish had urine thrown over him by a spectator during the Avranches to Mont Saint-Michel stage, a response, it would seem, to his collision with the Dutchman Tom Veelers the previous day. Cavendish's golden shower briefly overshadowed an ominous surge from Chris Froome, who retained his own yellow jersey after finishing second on the stage ahead of Alejandro Valverde. "To do something like that is sad and it leaves a bad taste in the mouth," Froome sympathised afterwards, gargling with Dettol, before surging up the fearsome Mont Ventoux, becoming only the second man in yellow ever to win the stage.

Boxing getting theatrical

In Hull British Olympic bantamweight gold medallist Luke Campbell began the traditionally fraught journey towards becoming post-Olympic contender Luke Campbell with a first-round stoppage of Andy Harris in his first paid fight. The whole thing took 88 seconds. Meanwhile, two of boxing's most extrovert and frankly quite odd characters, David Haye and Tyson Fury, have announced they will engage in a risibly overcooked "grudge match" on 28 September. Time to dig out the angry face again. Grrrr.
